DESCRIPTION
EN Detecting movement
The sensitivity of the detector
has been designed to detect the
human form including of course
children and it is therefore
possible that some animals,
principally large dogs, will also
switch the system. This is
unavoidable but, in most
instances, offers an advantage as
unwanted animals
frightened
away by sudden lighting.
As long as motions are detected
the connected lights remain
switched on. The sensor would
switch off the light after the
preadjusted time. If motion is
detected again immediately
after the switch off, the detector
can only be reactivated again by
motions after 3 Sec.
The detector is equipped with a
semiballsize-fresnel lens which
gives a semicircular detection
field (horizontally appr. 180°,
vertically appr. 60°).
regards to the recommended
fixing height of 1.10 - 2.20 m and
to a motion transversally to the
lens segments the radius of the
detection field is appr. 10 m.
Acoustic function
As long as the acoustic sensor
receives noises e.g. by TV,
speech or music the detector
remains switched-on even when
there are no more motions the
light stays on. Every noise and
every motion retriggers the unit
again for the period of
preselected time.
Unless there is no more motion
and no more noise, the detector
would switch the light off
automatically.
Immediately thereafter the
detector can be switched on
again e.g. by making sound
when this would be done within
a period of 8 sec. However has
the detector not been activated
for a longer period, then the
are
unit can be retriggered only by a
motion.
This combination protects the
unit to be switched on by
unwanted noises.

Prior to installation:

Before installation by all means
the following aspects have to be
considered:
• The detector is designed for
the installation in standard
switch flush mounted boxes.
The recommended fixing height
is 1.10 to 2.20 m.
With • Not more than eight detectors
can be switched parallel, in
order to avoid potential fault
switching.
• There must be no obstacles in
the view of the motion detector,
since infrared rays cannot
penetrate solid materials.
• The detector is an automatic
light switch which cannot be
used for intrusion applications.
Selection of fixing place:
The optical system of the
detector is designed for fixing
heights of 1.10 to 2.20 m.
A typical application is the
replacement of a wall switch in
appr. 1.10 m height or for room
surveillance in 2.20 m height.
Additionally to the horizontal
detection plane the detector has
a vertical detection plane which
detects also movements
underneath the motion
detector.
The maximum range is 10 m,
independently of fixing height.
The range cannot be adjusted
electronically or manually,
instead unwanted detection
areas have to be eliminated by
adhesive tape that must be put
on the corresponding lens
segments.
Frontal approach
Motion detectors are most
sensitive when motions are
across the detection zones. In
case of a frontal
approach the sensitivity and
hence the range is considerably
reduced.
Adjustment of twilight-
switch and acoustic-sensor
Lux-level setting (Photocell)
The lux-level can be set between
2 and 2000 Lux
Night operation
Day and night operation
On-period / switch-off delay
time
The switch-off delay time can be
set from ca. 15 sec. to 16 min.
(When setting into operation it
is
4
recommended to use the shortest
time setting for convenient
testing of range and noise
sensitivity
Noise sensitivity
Fully counter clockwise means
highest sensitivity. Fully
clockwise means noise detector
switched off. Intermediate values
to be adjusted accordingly to
local conditions. Functioning of
the noise detector will be
indicated by a LED located behind
the lens.
Lighting of the LED means the
noise detector is functioning and
triggers the timer again.
